This commit message is duplicated in multiple commits, and does not 
really describe the problem you're fixing. Since you've already updated 
the IPC API docs to ask caller to free even in case of failure, i think 
here (and in other similar patches) it is sufficient to just say 
something like:

When sending synchronous IPC requests, the caller must free the response 
buffer even if the request returned failure. Fix the code to correctly 
use the IPC API.
